MOTOR FOR SEWING-MACHINES.

$PECIFICATION forming part of Letters Patent No. 260,066, dated June 27,1882.

Application ined April 24, ieee. (No model.)

provements inl Motors for Sewing-Machines, of

which the following is a specification.

My invention consists 'of a new and useful improvement in motors forsewing-machines, as will be hereinafter fully set forth.

V In order that those skilled in the art to which my inventionappertains may fully understand the same, I will proceed to describe itsconstruction and operation, referring by letters to the accompanyingdrawings, in Which'- Figure l represents a perspective view of myimproved device secured in position against the wall of a room andconnected by a belt to the driving-pulley of a sewing-machine; and

IFig. 2 is a side view of the saine, illustrating more fully thespeed-regulating brake.

Similar'letters denote like partsin both views.

A represents a metallic frame, provided at suitable points withscrew-holes B, by means of which the frame may be readily secured inposition against the wall of a room or building. The upper end of theframe is turned over in front to form a bearing for one end ot the shaftof a double drum, C, the other end of said shaft bearing. in the frame.

D is an arm projecting horizontally from the frame A, nearits lower end,and adapted to have secured to its outer end a pinion, E, and beltpulleyF.

The drum C is provided at its outer end with a head, Gr, the peripheryof which is formed with teeth adapted to engage with the cogs of thepinion E and to communicate power and` of the drum is provided withanother cable, L, wound in the opposite direction, so that the descentot' the weight Kwill wind up the cable L and the unwinding of the cableL will lift the weight K.

In order to regulate the speed of the motor,

I apply to a bracket, M, vextending from oneA side of the frame A, africtionbrake consisting of an arm or lever, N, provided at one end witha rubber or other friction-wheel, O, and at the other with a cord, l.

Behind the upper leg ofthe lever N is arranged a spring, Q, adapted tohold the wheel O in contact with the drum O, so that it can only bereleased by pulling on 'the cord P.

lt will thus be seen that the action of the springQ and the consequentamountof friction produced may be readily regulated by a draft upon thecord P, which may be fastened to the frame of the sewing-machine or tothe treadle thereof, so that by the pressure of the foot upon thetreadle the machine may be put in motion and its speed regulated.

Multiplying-gears may be interposed between the pinion E and thedrumllcad G, if thought desirable to retard the descent of the weight.When the weight shall have reached the floor or uncoiled the full extentof its connectingcable it is again lifted .to an operative position bypulling the cable L from the drum.

What I claim as new, and desire to secure by Letters Patent, is-

The frame A, curved or bent overat the top and provided near theopposite end with an arm, D, in combination with the drum (l, head G,pinion E, pulley F, brake N O, cordY P, belt H, and weight and cord,substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
